He explains that identifying eucalypt trees and assigning the common names can be challenging, since titles can vary between regions.

"If you look at the South Australian blue gum for example, in Victoria they call that yellow gum and in NSW they call it white ironbark, so regional names can make things confusing.

"The common names can come from all sorts of sources. There's common names that may be of aboriginal origin, or those that relate to the colour of the wood- red gums are a good example there with the red colour of their wood."

Mr Nicolle has been involved in the naming of several new eucalypt species, and says it's actually quite an involved process.

"When you come across something that looks a bit different it's not a matter of knowing it's instantly a new species- there's a lot of research, the seedlings need to be grown, and it needs to be compared to other populations.

"So it can be a long term study to work out whether something's different or not, and certainly there's still unnamed eucalypt species in South Australia."

He said 10% of Australia's 900 types of eucalypt exist in the state, and they're of varying popularity among the public.

"Some of my favourite species are the ones that have more character, the type that some people love and some people hate," Mr Nicolle said.

"There are forest eucalypts in South Australia in some of the higher rainfall areas, but the eucalypts with the real character are often the longer limbed desert species, and woodland species from more arid areas."

Mr Nicolle says people that aren't already fond of the native Australia species should remain open-minded.

"When some people hear about gum trees they think of dirty great big red gums, the type of trees that can drop the odd branch and cause problems if you're living underneath them.

"But of course there's all the smaller growing eucalypt species, and there's a lot of species that are perfectly safe to live under, and close by.

"So sometimes eucalypts get a bit of a bad wrap, but because there's so many different species, there's lots of really good ones out there."
